System Requirements

For the InDesign plug-in

For the app builder application

The Twixl Publisher application requires the latest version of either macOS High Sierra 10.13, macOS Sierra 10.12 or OS X 10.11 El Capitan.

For creating iOS apps

Xcode will allow you to get a preview of your application in the iOS simulator on macOS (but trust us, you'll never need to open the application itself ;-). The System Check at startup will automatically check for the presence and offer a link to install it if Xcode is not installed.

Xcode for macOS High Sierra and Sierra is a free download from the Mac App Store

In order to create app builds that can be installed on a device, or to submit apps in the App Store, you need at least Xcode 9 and need to be registered as a developer in the "iOS Developer Program" (99$/yr): Start here to enroll now.

For creating Android apps

Android SDK: the Android SDK needs to be available to create Android builds. The System Check at startup will automatically check for the presence of the Android SDK and offer to install it if it's unavailable.
